Morphogenetic manipulation of algal endosymbionts in a widespread 
planktonic photosymbioses

Abstract: Phaeocystisis a globally abundant bloom-forming phytoplankton 
genus that contributes substantially to global carbon and sulfur 
cycling. Phaeocystis’ unique life-history—which includes solitary 
flagellated, colonial, and endosymbiotic phases—contributes to its 
ecological success. In my Ph.D. research, I investigated the nature of 
Phaeocystis’ relationship with a symbiotic host—the acantharians, 
another group of unicellular plankton—through the use of single-cell RNA 
sequencing and advanced imaging techniques. My results showed that 
acantharian hosts collect Phaeocystissymbionts on multiple occasions, 
but maintain symbionts for extended periods of time. While inside hosts, 
Phaeocystissymbionts are heavily manipulated and undergo a drastic 
morphogenetic transformation. Ultimately, the acantharians transform 
Phaeocystisinto internal photosynthetic engines. At WHOI, I am pivoting 
my focus toward the colonial life-stage of Phaeocystis. The 
mucilaginous, carbon-rich colony matrix is a unique interface for 
bacteria-phytoplankton interactions. I am investigating how these 
interactions may influence Phaeocystisbloom development and will present 
preliminary results.
